meter : both the valves are deeply hollowed, and, when clofed and viewed tideways, 
have much the appearance of the figure of a heart at cards: the fubftance of the (hell 
is tolerably firm and folid, it is lightly fafciated, and the intermediate furface is fmooth, 
and has a fine polifh; the colour is white, with a tinge of red. 
We have this fpecies in fome of our large rivers, but it is not common. 
The other fpecies of the frefh-water Cardise are, 1. The larger, fmooth, brown 
Cardia. 2. The larger, pale red, ffriated Cardia. 3. The little furrowed, whitifh, 
round Cardia. 4. The little, fafciated, olive-coloured Cardia. 5. The leffer, flat, 
furrowed Cardia, called the frefh-water Scallop. 6. The larger, flat, furrowed Cardia. 
Thefe are all the known fpecies of the bivalve frefh-water fhells: as to the feveral 
genera of the multivalves, we have not yet met with a Angle fpecies of any one of 
them, that is an inhabitant of any water but fuch as is fait.

T HI S is the largefl: of the fnail kind known among us: it is more than an inch 
_ in height, and as much in diameter 5 the fhell is confiderably firm and firong, 
and the colour a deep dufky brown, variegated with clouded fpots and oblique fireaks 
of a paler brown ; and fometimes, but not always, there runs a fpiral line of the fame 
brown, following the volutions of the fhell: the body of the fhell is rounded, and 
the mouth nearly round, but a part of it filled up by the fucceeding volution of the 
fhell: the clavicle is elated, and has four volutions. 
We have this fpecies in fome parts of Surry, but it is not frequent: it is not pro¬ 
perly a native of England, but of the warmer parts of Europe; there are people who 
remember the time of a large quantity of them being brought over from France, for 
the ufe of a perfon of quality in that part of the kingdom, to whom they were pre¬ 
ferred as a medicine : they came over alive, and were turned loofe in the garden, and 
from that parcel all the country about has been furnifhed with them; and many other 
places from thence.

This is the largefl of our ordinary fnails, but it is confiderably fmaller than the

body of the fhell is rounded • the mouth is large, and approaches to a round figure., 
but is in part filled up by the fucceeding volution of the {hell 5 the clavicle has four

runs a broad Ample fafeia or belt along the body, following the fpiral turn of the fhell, 
and fometimes there are two other faint ones: above and below this middle fafeia, 
there run feveral broad and fhort oblique lines or clouds of a different brown. 
It is extreanily common in our gardens, and under hedges.
